Linux, the free operating system, has gone from an intriguing experiment to a mainstream technology in corporate data centers, helped by the backing of major technology companies like IBM, Intel, and HP, which sponsored industry consortiums to promote its adoption. Linus Torvalds, the creator of Linux, with the system's penguin symbol, will assist the Linux Foundation. Those same companies have decided that the time has come to consolidate their collaborative support into a new group, the Linux Foundation, which is being announced today. And the mission of the new organization is help Linux, the leading example of the open-source model of software development, to compete more effectively against Microsoft, the world's largest software company.
